Mirror each user's own YouTube playlists into local source='youtube' playlists, one-way (YT -> local). New client methods iter_my_playlists / iter_my_playlist_video_ids (OAuth, so private playlists work); sync/playlists.py reconciles the mirror (matching YT order) and ingests any playlist videos not in the shared catalog yet (with stub channels). POST /api/playlists/sync-youtube for manual sync (read-scope gated, per-user quota) plus a scheduler job (playlist_sync_minutes, default 6h) that syncs all read-scope users. YouTube's Watch Later / History are not API-accessible and are never synced.
